Abstract

IntroductionCorrect lung cancer staging is pivotal for optimal allocation to surgical and nonsurgical treatment. A left adrenal gland (LAG) mass is found in 5 to 16%, and malignancy preclude surgery. Endoscopic ultrasound (EUS) is superior to other imaging procedures in visualizing LAG, but the impact of EUS-fine needle aspiration (FNA) on tumor, node, metastasis (TNM)-staging, treatment, and survival is unknown.MethodsThe impact of EUS-FNA of the LAG on TNM staging, treatment, and survival was evaluated retrospectively in all patients (n = 40) referred to EUS during 2000–2006 for known or suspected lung cancer and where EUS disclosed an enlarged LAG. Conventional workup had preceded EUS.ResultsEUS-FNA of an enlarged LAG altered the TNM staging in 70% (downstaged: 26 of 28 patients) and treatment in 48% (gained surgery 25%, avoided surgery 5%, surgically verified benign disease 5%, no cancer and no further workup 5%, and no cancer, control computed tomography, and then no further workup 8%). A malignant LAG lesion was found in 28% and was significantly associated with shorter survival.ConclusionEUS-FNA of an enlarged LAG in patients with known or suspected lung cancer had a significant impact on TNM staging, treatment, and survival. The impact of routine visualization of the LAG in lung cancer workup needs to be prospectively validated.
